None of the global shortcuts work when I'm using any fullscreen game, including Alt+Tab.
I can't get out of the game until I use some kind of "exit" option, can't start/stop the music player...
This is especially annoying on my laptop, as fullscreen applications increase the brightness to the maximal value (which is another problem, but I think they have a common root), and I can't change it.
I use Kubuntu 11.10.
